IsDefault (MDStore Interface)

NoteNote

  This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.

The IsDefault property of the MDStore interface indicates that an MDStore object is the default partition of a cube or the default aggregation of a partition.

Applies To: clsAggregation, clsPartition

Boolean

Access depends on the value of the ClassType property of the object.

clsPartition

The default value for this property depends on the value of the ClassType property of the object.

Class type

Default value

clsAggregation

If you generate the aggregation by using an object of ClassType clsPartitionAnalyzer, the system automatically sets IsDefault to True. Generating aggregations in this way has performance benefits and is the recommended method for generating aggregations.

If you generate the aggregation without using a partition analyzer object, you should set IsDefault to False.

clsPartition

True if the partition is the only one in the cube, False otherwise.

NoteNote

  This property does not indicate that an aggregation object is the default within a collection of aggregations. If set to True, it indicates that the aggregation object contains the default dimensions and measures of the partition, which are already stored in the repository. This reduces the size of aggregation metadata, which can become important when a partition contains a large number of aggregations.
